I recently learned my kids’ favorite cereal, Cheerios, is full of GMO ingredients. Learning this made me wonder how common Genetically Modified Organisms, or GMOs, are in Colorado. To what degree do they impact our health and environment?

Like most technological innovations, GMOs were developed to solve a problem, improve our lives and make money. But many innovations heralded as societal boons eventually have unintended negative consequences as we learn more about them or as their usage becomes widespread.

GMOs are plants whose genes have been altered. People have been altering genes for millennia by selective breeding — whether they’re creating rose hybrids or dog breeds. The main difference with GMOs is genes are inserted into plants in the lab, in combinations that wouldn’t occur through traditional breeding or natural evolutionary processes. For example, papaya, zucchini and yellow summer squash have genes that were inserted to help the plants resist viruses, and cotton’s genetic modifications help it resist insects. Alfalfa, sugar beet, canola and soybean genes have been changed so they can resist certain herbicides. This allows farmers to spray the crops with glyphosate (i.e., Roundup) — which kills the weeds but not the crop.

Although hybrid and organic crops are grown here, the vast majority of Colorado crops are GMOs.

The kingpin of Colorado crops is corn — a billion-dollar industry. Unlike “sweet corn” sold in the grocery store, most Colorado corn is “field corn” for feeding animals or fueling cars. A fraction of our corn provides syrups, sugars and starches used for sweetening, thickening and stiffening food products ranging from pasta to vitamins. Twinkies are the ultimate byproduct of GMO corn — they’re made with corn starch, glucose, high fructose corn syrup and a bunch of other GMO ingredients I can’t pronounce.

Nearly half of Colorado’s corn is brewed into a special moonshine — ethanol. This alcohol is used as a pollution-inhibiting supplement in all gasoline and as the main ingredient in E-85 fuel. Ethanol production is so profitable in Colorado we import corn to keep up with demand.

Sugar beets are Colorado’s coolest and least-known GMO. Grown on the Eastern Plains, these beets look like ancient subterranean footballs. Their pulp becomes table sugar, which is later mixed into all sorts of products — from baked items to sauces. This $100 million dollar industry is efficient — sugar beet leftovers are used to feed cattle and other livestock. Soon sugar beets will be used to make ethanol, too.

But do such GMOs pose health or environmental risks? A preponderance of epidemiological data suggests GMO foods and GMO-derived food products pose no health risks. They have been studied judiciously by many scientists and approved for human consumption by the U.S. Department of Agriculture, World Health Organization and United Nations.

Yet for wildlife and ecosystems, the impact of GMOs is another matter entirely. GMO crops are nowhere near as environmentally friendly as organically grown crops, because the widespread spraying of weedkilling herbicides like Roundup exacerbates killing of beneficial critters like insects, frogs, birds and worms. The net result is reduced animal and plant diversity, battered ecosystems and unintended side effects.

For example, GMO agriculture has necessitated a massive increase in spraying of Roundup to kill milkweed. But so much milkweed has been destroyed that the entire North American monarch butterfly population, whose caterpillars exclusively eat milkweed, has been catastrophically devastated.

Other GMOs, however, have reduced demand for pesticides. Bt corn, for example, contains a gene that allows it to produce a protein toxic to certain insects, obviating the need to spray Bt corn crops with insecticides. This, in turn, reduces the unintentional biodiversity losses typically associated with insecticide use and minimizes pesticide-application risks for farmworkers.

So what’s the future of GMOs? More will come, including rice, potatoes, and one that could be a boon to Colorado — drought tolerant wheat.

There are some benefits and drawback to using GMOs, and time will tell whether the risks outweigh the rewards. But the genie is out of the bottle. GMOs are all around us — in our food, on our land and in our cars. Like Twinkies, they’re here to stay.
